What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
Does an inductor absorb electrical energy?
Yes, both capacitors and inductors are capable of storing energy. Capacitors store electrical energy in form of electrical charge and inductors in form of magnetic field. - Neeraj Sharma
How does a tank circuit circuit work?
A tank circuit is typically a combination of 'capacitive' and 'inductive' circuits that exchange 'energy' back and forth. An inductor stores energy as a magnetic field, wheras a capacitor stores energy as a charge across plates. Ideally, the exchange between them would go on forever (back and forth like a game of hot potato) however, a slight replenishing signal is needed practically. By selecting the proper values of components, the rate, or frequency, of exchange can be determined.
Is the resistance of the inductor is zero?
The power consumed by an inductor is not zero since it's resistance is not zero either. The power consumed is just too minimal that it can be ignored. What the inductor does is, during one half of the Current's sinusoidal waveform, it stores energy in the form of magnetic flux. During the next half,it discharges the stored energy into the circuit by losing the magnetic field. Hence,they say it doesn't consume power. If the inductor's resistance was significant then you will see that it will consume power. Resistance and Reactive resistance are two different things.
Explain the function of the capacitor and inductor in a power supply?
A capacitor resists a change in voltage (dv/dt = i/c). An inductor resists a change in current (dl/dt = vl). Together, a capacitor and inductor make a tuned circuit. Usually, in a linear power supply, there is a capacitor in parallel with an inductor in series, and often, in a pi filter, another capacitor in parallel. This reduces the peak to peak voltage at the output. It is also possible to put an inductor in series with the rectifier diode, as as to reduce inrush current. In a switching power supply, things are a little bit different. The primary inductor is a current pump, maintaining constant current flow to the load, controlled by the pulse-width oscillator which switches between on-current from source and off-current from schottky diode. The capacitor in this case filters the output, so as to reduce high frequency harmonics.
Why no power loss in pure inductance?
An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R

What is the purpose of a inductor?
The purpose of an inductor is to store and release energy in the circuit usually in order to induce a phase shift in the voltage or current passing through it. Inductor stores energy in the magnetic field.
What is a device used to store charge?
A capacitor stores an electric charge. An inductor stores a magnetic charge.
Might a synchoronous motor equally well be called a synchoronous inductor?
No. An inductor by definition is a passive component that stores electrical energy in an magnetic field. It does not use real power (in any serious amount). A synchronous motor is not passive, and uses real power.
Does an inductor absorb electrical energy?
Yes, both capacitors and inductors are capable of storing energy. Capacitors store electrical energy in form of electrical charge and inductors in form of magnetic field. - Neeraj Sharma
May I know the properties of an inductor?
Some of them are: 1. Inductor temporarily stores energy in form of magnetic field. It is given by E=½LI² here L is inductance & I is current. 2. Inductor causes current to lag voltage by 90°. 3. Inductor consumes reactive power. 4. Inductor oppose current change in circuit for AC only. Fo DC it act as simple wire. 5. Inductors are used for blocking the AC while passing the DC. They are known as chokes. 6. Inductors are used to create magnetic fields in electrical machines for the purpose of energy conversion.

Is that true a capacitor stores energy in the form of a magnetic field?
Simple answer: Yes. If there's electricity, there is a magnetic field. I'm guessing that you're thinking that alternating current reverses current flow, as opposed to direct current. This isn't quite right. A.C. works by alternately advancing and reversing the movement of charge, basically pumping electricity down a wire. Capacitors store charge. That's all they do until some part of a circuit lets them release it. So a capacitor connected to an a.c. source will just store charge and a magnetic field will certainly be attached.
Do magnetic fields store energy?
of course, they do. A research project show that a motor constructed with magnets at specific directions & positions can run for atleast 100 years without break.But the magnets are not to be disturbed & also they don't have to be charged
